Chun Chun was born in a caesarean section which lasted around 20 minutes on Saturday. Both the mother and baby boy are doing fine, according to doctors who spoke with the Chinese newspaperDahe Daily.

It may be added for information that the heaviest birth listed by Guinness World Records belongs to a baby boy born in 1879 in Ohio, who weighed 23 pounds 12 ounces at birth and whose mother was said to be a "giantess." Unfortunately, the baby died 11 hours after birth.
